# Now we have read data into arrays, we can draw the chart using ChartDirector
#
# Create a XYChart object of size 600 x 360 pixels
$c = new XYChart(600, 360);
# Set the plotarea at (60, 40) and of size 480 x 280 pixels. Use a vertical gradient
# color from light blue (eeeeff) to deep blue (0000cc) as background. Set border and
# grid lines to white (ffffff).
$c->setPlotArea(60, 40, 480, 280, $c->linearGradientColor(60, 40, 60, 280, 0xeeeeff,
0x0000cc), -1, 0xffffff, 0xffffff);
# Add a title to the chart using 18pts Times Bold Italic font
$c->addTitle("Annual Revenue for Star Tech", "timesbi.ttf", 18);
# Add a multi-color bar chart layer using the supplied data
$layer = $c->addBarLayer3($revenue);
# Use glass lighting effect with light direction from the left
$layer->setBorderColor(Transparent, glassEffect(NormalGlare, Left));
# Set the x axis labels
$c->xAxis->setLabels($timestamp);
# Set y-axis tick density to 30 pixels. ChartDirector auto-scaling will use this as
# the guideline when putting ticks on the y-axis.
$c->yAxis->setTickDensity(30);
# Synchronize the left and right y-axes
$c->syncYAxis();
# Set the y axes titles with 10pts Arial Bold font
$c->yAxis->setTitle("USD (Millions)", "arialbd.ttf", 10);
$c->yAxis2->setTitle("USD (Millions)", "arialbd.ttf", 10);
# Set all axes to transparent
$c->xAxis->setColors(Transparent);
$c->yAxis->setColors(Transparent);
$c->yAxis2->setColors(Transparent);
# Set the label styles of all axes to 8pt Arial Bold font
$c->xAxis->setLabelStyle("arialbd.ttf", 8);
$c->yAxis->setLabelStyle("arialbd.ttf", 8);
$c->yAxis2->setLabelStyle("arialbd.ttf", 8);
# Create the image and save it in a temporary location
$chart1URL = $c->makeSession("chart1");
# Create an image map for the chart
$imageMap = $c->getHTMLImageMap("dbdemo3a.php", "",
"title='{xLabel}: US\$ {value|0}M'");
